Fluid-velocity measurements and flow-pattern identification by noise-analysis of light-beam signals

, 1983
For fluid-velocity measurements of the two-phase flow in reactor safety experiments, a new method has been developed. This method is based on cross-correlating the signals of two light-beam detectors, which cross the diameter of the test-section (no flow
